Using M32_Card for Data Acquisition with on-board 8 channnel ADC

Hi friends,
I'm showing here one more application of the home-made M32_Card discussed in my earlier post. The microcontroller of the card is having 8-channel, 10 bit resolution ADC which can be used for analog data acquisition. Using the hyper terminal for the selection of menu, ADC can be selected to display value of the analog voltage applied to each channel (at the 9-pin header pin; 8 ADC channels & 1 GND).
The microcontroller reads the voltage at each channel and sends the data to PC via RS232 cable. At reciving end (PC), the incoming data can be converted into excel format to store the values at regular time intervals.
As shown in the screen-shot of the hyper terminal, I had connected here the 5v Vcc to Channel 0 and an Li cell to channel 7.
The M32 can also send a time impression along with the channel data using the on-board RTC DS1307 to record the voltage variation with time.

Safe Landing, Welcome!!

Hi techies,this blog is created for sharing design ideas of circuits based on microcontrollers!! Be it any controller, i don't mind! my favourite microocntrollers are AVRs from Atmel (Microchip)Have a say if you find anything useful or the opposite on this blog!! You can also share your comments on the designs!
